You can obtain the Amiga OS3.x includes from these links, for example :

What programming language do you guys use to write your Amiga applications?

There are many that can be used.

I can see often people using on amiga OS 3.x :

- ASM 68K, using VASM or Devpac (many others are available)
- C Lang, much more suitable for Amiga than C++, using GCC, VBCC, SASC
- Amiga E using ECX for Amiga
- Some use also AmiBlitz, Amos, Pascal, ...
